Surge protection device recommended
This product contains sensitive electrical components that may be damaged
by electrical spikes, surges, electric shock, lighting strikes, etc. Use of surge
protection systems is highly recommended to protect and extend the life of
your equipment. Set top boxes (cable and satellite) can pass surges through
the HDMI connection, a Simplified MFG HDSURGE is suggested.

17 HDMI IN Port
This is a 1080p 24Hz. send back to the HDMI OUT port on TX.
This return path to the TX is defaulted to closed and must be
enabled with a command via Hercules or similar program. The
eARC/ARC path is then inoperable and eARC/ARC should be
disabled.

upgrading the HDBaseT firmware
DIP = Numbers 2 and 3 at “11”, RS-232 is in debug mode
5.3 USB Mode Applications
The USB functions can be adjusted so that either the TX or the RX can
become the host or the client. Simply use the Host/Device to choose the
function and power cycle the RX and TX for it to take effect.
Example 1: TX Host, RX Client
Set the Host/Client switch on TX to “Host”, set the Host/Client switch on RX to “Client”
and power cycle the RX and TX.

11 / 15
Example 2: TX Client, RX Host
Set the Host/Client switch on TX to “Client”, set the Host/Client switch on RX to “Host”
and power cycle the RX and TX.
5.4 IR Pin Definition
IR Receiver and Blaster pin’s definition is as below:
Note: When the angle between the IR receiver and the remote control is ± 45 °, the
transmission distance is 0-5 meters; when the angle between the IR receiver and
the remote control is ± 90 °, the transmission distance is 0-8 meters.

12 / 15
6. Application Examples

13 / 15
A 1080p @ 24Hz. Video return path can be opened by sacrificing the eARC/ARC feature.
This is done by disabling the eARC/ARC with the button on the TX and RX and then
sending a command to tell the TX to switch to this mode. This is done using Hercules
(the link is on the M88SL webpage at www.simplifiedmfg.com/m88sl) and it is freeware.
You will need to set the RS-232 DIP switch on the TX to “01” and then send the correct
command to set the HDMI loop out to output the return video. Using the serial portion
of Hercules, use these settings;
Baud rate:115200, Data bits:8, Stop bits: 1, Check bit: 0
Send the command “s loop-out in 2!”, to put it back to loop-out from source send the
Command “s loop-out in 1!”. If you want to poll the device to see which mode it is in,
you would use the command “r loop-out in!”

14 / 15
Other commands are:“r fw version!” – display’s devices current firmware
“s reboot!” – reboots the device
“ s reset!” – sets the device to factory defaults
